I-PEX 82288-100B-02-D 30P high-speed signal transmission ultra-thin coaxial cable replacement

One, for high-density high-speed connection requirements, analyze the I-PEX 82288-100B-02-D ultra-fine coaxial cable assembly

Under the background of continuous development towards thinness and high-speed of electronic products such as laptops, tablets, high-speed display devices, and data communication equipment, the internal wiring harnesses of these devices not only need to meet the requirements of high-speed signal transmission but also need to take into account high-density wiring, EMI shielding, and connection reliability within a limited space. The I-PEX CABLINE®-CA II is a level plug-and-play ultra-fine coaxial connector platform specifically designed for such applications, supporting different specifications such as 20Pin, 30Pin, 40Pin, and 50Pin, and adopting ZenShield® full shielding and mechanical locking structure.

This article focuses on the target product I-PEX 82288-100B-02-D, which corresponds to the official information of CABLINE-CA II 30Pin Micro-Coaxial Harness, 40AWG, L=300mm, 1-N. According to the aforementioned product drawings, this harness uses 30 extremely thin coaxial wires, with wire specifications of AWG 40, 50Ω Micro-Coaxial Cable, and a nominal length of 300mm, and is connected to the CABLINE-CA II 30Pin connector. The Plug Housing model connected to the wire material is 20680-030T-01, corresponding to 30Pin, 0.4mm contact spacing. The I-PEX official information also lists that 20680-030T-01 belongs to the CABLINE-CA II 30Pin Plug Housing, with its配套Shell being 3204-0301 and Lock Bar being 20681-030T-01.

For engineers, the value of this wiring harness is not just in it being "a harness composed of 30 wires," but in the combination of extremely thin coaxial cables, connectors, shielding structures, Pin definitions, termination processes, and overall size control that form a high-speed signal connection component. For purchasers, what truly needs to be concerned with is not just whether the material numbers are consistent, but also to confirm the Pin count, Pitch, wire AWG, impedance, wire length, connection direction, termination form, and whether the actual device's plug-in port matches. Therefore, when looking for alternative suppliers, the complete engineering specifications should be used as the basis for judgment, and not just rely on appearance or connector names for substitution.

Why is the 30PIN important? What are the differences between different Pin numbers of extremely thin coaxial cable connectors?

For extremely thin coaxial cable assemblies, the number of connector pins primarily represents how many independent contact positions and signal channels can be provided. The I-PEX CABLINE-CA II currently offers specifications for 20, 30, 40, and 50 Signal Pins. Therefore, 20Pin, 30Pin, 40Pin, and 50Pin are not simply different "connector sizes"; they correspond to different system signal quantities and PCB routing requirements. For example, the target model 82288-100B-02-D uses a 30Pin structure. If the original design of the device requires 30 connection paths and a direct switch to a 20Pin connector is made, issues such as insufficient signal channel numbers, non-corresponding Pin definitions, and incompatible PCB layout may arise; conversely, if the device originally used 30Pin, it cannot be simply replaced with a 40Pin just because it has more contacts, as the connector's physical dimensions, PCB Footprint, mating relationship, and system space will all change with the number of pins.

From the perspective of size, an increase in pin count usually means an increase in the lateral size of the connector. According to the official I-PEX documentation, the width relationship for CABLINE-CA II is given as 6.95 + 0.4 × Pin Count mm. Therefore, according to this formula, the theoretical widths for 20Pin, 30Pin, 40Pin, and 50Pin are approximately 14.95mm, 18.95mm, 22.95mm, and 26.95mm, respectively, while the contact spacing remains at 0.4mm. This means that engineers cannot only look at the pin count when doing PCB layout, structural design, and internal routing planning; they also need to consider the space occupied by the connector. At the same time, different pin counts will also affect the overall out-line density, bending space, and assembly difficulty of the cable harness. For purchasing personnel, the 30Pin product cannot be simply understood as "all 30Pin are universal"; further verification of the specific connector series, Housing model, Shell model, Lock Bar model, and mating socket is required.

In addition, the number of pins and the cable specification should be considered together. CABLINE-CA II supports Micro-Coaxial Cable specifications such as AWG36, AWG38, AWG40, AWG42, and AWG44; the official documentation states that the AWG40 has a current capacity of 0.3A/contact, with a maximum of 50 contacts. However, this does not mean that cables with different numbers of pins can be directly interchangeable, but rather it indicates that AWG40 can cover the different pin count schemes of CABLINE-CA II when the corresponding design conditions are met. Therefore, for the combination of 30 pins, AWG40, and 0.4mm pitch in this article, it is more important to ensure that the entire cable assembly remains consistent with the original device's signal definitions, connector structure, and high-speed transmission requirements.

How do engineers and purchasing personnel make selection? Reference and suggestions for compatibility and alternative solutions for 82288-100B-02-D

For the compatible alternative of I-PEX 82288-100B-02-D, engineers are advised to first lock the core specifications of "30Pin + 0.4mm Pitch + AWG40 Micro-Coaxial Cable + 300mm + 1-N", and then further check the connector end structure and the mating connector on the equipment side. The official sample materials of I-PEX clearly define 82288-100B-02-D as 30Pin Micro-Coaxial 40AWG, L=300mm, 1-N, while the same series also exists 82287-100B-02-D (100mm) and 81461-100B-02-D (200mm) 30Pin 1-N cables, so the cable length itself is also an important parameter that must be checked during selection. If the actual installation space of the device requires 300mm, and the 200mm model is mistakenly selected during procurement, even if the pin count and connector series are the same, it may not meet the whole machine assembly requirements.

In terms of connectors, the cable harness to be used has a wire end connector housing model of 20680-030T-01, which is the CABLINE-CA II 30Pin Plug Housing; the corresponding 30Pin Plug Shell model is 3204-0301, the Lock Bar model is 20681-030T-01, and the recommended material number for the 30Pin Receptacle on the equipment PCB side is 20682-030E-02. Therefore, when developing alternative cable harnesses, the complete chain of "wire end connector - equipment end socket - cable - Pin definition" should be verified, rather than just verifying the wire end Housing model. For high-speed signal applications, impedance, insertion loss, return loss, crosstalk, shielding continuity, and the integrity of high-speed signals in the finished cable harness should also be verified in combination with the actual project requirements.

From the perspective of supply chain and procurement, if there are issues with delivery times, MOQ, cost, supply stability, or customization response from the original factory cable, a compatible alternative solution can be considered for evaluation. Our company can provide the I-PEX 82288-100B-02-D compatible alternative cable solution, which can be developed and produced around core specifications such as 30Pin, 0.4mm Pitch, AWG40 ultra-thin coaxial cable, and 300mm length, and can be confirmed for engineering based on the actual connector, Pin definition, length, wiring direction, and assembly requirements of the customer's equipment. For customers in need of domestic alternatives, second supplier introduction, or bulk purchasing, the alternative introduction can be gradually completed through sample testing, specification comparison, and high-speed signal performance verification.

Four, from the connector pin count to the entire harness: how to determine if the substitute product is truly "compatible"?

The most important principle for determining whether a very thin coaxial cable can truly replace the original model is: it is not enough to just look at "Pin number being the same," but rather to consider whether the "connector, cable material, dimensions, electrical performance, and application environment" are all matched as a whole. Taking the I-PEX 82288-100B-02-D mentioned in this article as an example, 30Pin is just one of the key identification conditions; it is also necessary to pay attention to information such as 30Pin, 0.4mm Pitch, 20680-030T-01 line-end Housing, AWG40 Micro-Coaxial Cable, 300mm cable length, and 1-N structure. The official information from I-PEX indicates that CABLINE-CA II uses a 0.4mm Pitch, horizontal insertion and removal, 0.95±0.15mm height match, and supports full shielding ZenShield® and mechanical locking structure. These structural features collectively determine its actual application method in high-speed, miniaturized equipment.

For engineers, it is recommended to use the original factory drawings as the basic reference for alternative development. Check and confirm the connector shape, pin numbering and corresponding relationships, wire specifications, characteristic impedance, harness length, adhesive fixing area, and wire exit shape, and further conduct electrical and high-speed signal tests according to the project requirements. For purchasing personnel, it is recommended not to only provide the simplified model "I-PEX 82288" during quotation inquiries, but to clearly specify key information such as 82288-100B-02-D, 30Pin, AWG40, 300mm, CABLINE-CA II, 20680-030T-01, in order to reduce supplier misunderstandings and improve quotation and sample efficiency.

What's more important is that different pin numbers represent different system connection capabilities and structural dimensions. 20Pin is suitable for solutions with fewer signal channels, 30Pin is suitable for designs like this with 30 channels, and 40Pin and 50Pin can provide more contact points, but at the same time require more lateral space. Therefore, when faced with different equipment and PCB designs, engineers need to choose based on actual signal quantities, board-end space, cable routing, and high-speed performance requirements, while procurement personnel should convert these engineering parameters into clear procurement specifications. In this way, situations like "pins appear to be the same but cannot be assembled in reality" or "the connector can be inserted but the high-speed signal performance does not meet the requirements" can be avoided.

I-PEX 82288-100B-02-D is a 30Pin, 0.4mm Pitch, AWG40 ultra-fine coaxial cable assembly product, whose core value lies in high-density connections, miniaturized structures, and ultra-fine coaxial cable designs for high-speed signal applications.
